I am having trouble with my PMs. Can someone tell me what I am doing wrong? Sometimes they send, and other times when I click on 'submit' they move to my 'outbox' and then refuse point blank to move to my 'sentbox'. I know I am missing something obvious

Hmmm...... .........Not a computer whiz here, but if replying to a pm sent to me, I hit post reply, then submit.....it goes thru. If sending one, click on the pm of that poster, fill out the form and hit submit........should work........sending you one to test it out.
